1 PAUL M. GAULT O F ST. LOUIS, MISSOURI a I {SI NALING SYSTEM Application. filed The in-ventionrelatesto a signaling syssee that the incoming freight trains are properly switched andIrouted to the particular depend on several conditions of which the yardattendant only has knowledge, as for example,'the nature of the freight, the particular vwholesaler to whom the freight is consigned, and the various tracks which at the time may be-vacant. It has therefore been necessary for the engineer of an lncoming freight train to stop at the entrance to the yard and communicate with the yard attendant to ascertain the particular track to which his train is assigned.

The invention has for its primary object the provision of a novel mechanism which will serve as an indicator for lncommg freight trains upon which signals can be flashed showing the particular tracks selected for the various trains.

Yet another object is to provide a device of simple construction which will be situated at the entrance to freight yards and serve as a means of information to the engineers of incoming trains, and thus obviate the delay in communicating with the yard attendant.

Another-object is to provide an indicator for use in freight yards which can be operated by a yard attendant conveniently while at a distance from the device.

These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheet of drawing, in which' Figure 1 is a diagrammatic layout of a freight yard showing the system of tracks employed and the storage facilities or freight sheds associated therewith;

Figure 2 is a fragmentary front elevation of an indicator embodying features of the present invention; and

A diagrammatic layout of a typical freight yard is disclosed in set of tracks 10 are operated by a certain railroad, and tracks 12 areownedand-operated by a subsidiary or competing I'Oad WhlCh roads use a' common freight yard and shed, as is often the case. However, tracks lO and 12 may comprise a and maintained by the same road. The tracks are united to form a main track formation by suitable switch means such as 16. Various sidings or lengths of track 18 form the yard, and on them the freight cars are L run to be unloadedv and,.'under some conditions, I reloaded with differentffreight. and

consigned to other points.
